Madonna and Diplo make cameo at DJ set by Arcade Fire's Win Butler

Madonna began her world tour in Montreal this week (September 9), inviting Diplo onstage before joining Arcade Fire's Win Butler during his DJ set in the Canadian city a day later.

Madonna's 'Rebel Heart' tour kicked off on Wednesday, with Diplo (who was a support act at the show) being spanked onstage by the singer and then handed a banana.

On Thursday night, Diplo and Madonna were brought out by Butler during his appearance under the name DJ Window 98 at the Phi Centre in Montreal.
